During any IVF (in vitro fertilization) procedure, eggs and sperm are combined external to a woman's body. These fertilized eggs are then allowed to develop into embryos. Eventually, one or more of these embryos will be placed inside the uterus – a process called embryo transfer.
What is fresh embryo transfer?
During fresh embryo transfer, one or more recently developed embryos from the current cycle of IVF are transferred into the uterus as soon as they are ready – often 3 to 6 days after egg retrieval.
The Embryo Transfer (FET) process involves taking embryos which have been cryopreserved (frozen) previously and placing them into the uterus.
